Natural products are compounds or substances found in living organisms in nature. In the broadest sense, natural products include any substance produced by life. Natural products are mainly obtained by chemical isolation, but can also be prepared by chemical synthesis (semi- and total synthesis) and provide challenging synthetic targets for the field of organic chemistry. We offer natural products such as flavonoids, alkaloids, quinones, terpenoids, lignans and coumarins in addition to those in our product classification.
Volatile oils, also known as essential oils, are a general term for a class of oily liquids that can evaporate at room temperature, can be distilled with water vapor, and are not miscible with water. Most of the volatile oils have aromatic odor, the solubility in water is very small, but can make water with the special smell of volatile oils and biological activity, volatile oils are often stored in the plant tissue epidermis of the glandular hairs, oil chambers, oil cells or oil ducts, most into the state of oil droplets exist.
Saponins are a special class of glycosides widely found in the plant kingdom, which are named after its aqueous solution that produces a persistent soap-like lather when shaken. Saponins are glycosides formed by the condensation of steroidal or triterpenoidal saponin elements with sugars or glyoxalates. They are widespread in the plant kingdom and are found in monocotyledons and dicotyledons, especially in the Dioscoreaceae, Ginseng, Liliaceae, Wujia, Leguminosae, Yuanzhi, Erythrinaceae, and Staphylinidae, where they are most commonly distributed and have a high content, such as Dioscorea, Ginseng, Chaihu, Licorice, Zhiwu, and Erythrinaceae. In addition, they are also found in marine organisms such as sea cucumbers, starfish and animals. The saponin ligands are divided into two categories according to their structure: steroidal saponins, mostly found in plants of the lily family and Dioscoreaceae, and triterpenoidal saponins, mostly found in plants of the Pentacostaceae and Umbelliferae families. Based on the structure of the saponin elements generated after hydrolysis, saponins can be divided into two major groups: triterpenoid saponins and steroid saponins.
Polysaccharides consist of monosaccharides linked by glycosidic bonds, which are polar complex macromolecules with a degree of polymerization greater than 10, and the basic structural unit is glucan, whose molecular weight is generally tens of thousands or even millions. It is widely distributed in animals, plants and microorganisms, and as a natural macromolecular compound from cell membranes of higher plants and animals and cell walls of microorganisms, it is one of the four basic substances constituting life activities. There are hundreds of active polysaccharides found so far, and they can be divided into 5 major categories according to their sources: fungal polysaccharides, higher plant polysaccharides, algal lichen polysaccharides, animal polysaccharides and bacterial polysaccharides.
In addition to small molecule natural products such as moth sex pheromones, large molecule natural products such as nucleic acids and proteins also exist in nature. It is well known that nucleic acids are important carriers of life's genetic information, and proteins are the material basis of life. Natural products are not only biologically important to the organisms that produce these compounds, but also play an increasingly important role in the daily life of human beings. For example, many fragrances and fragrance oils extracted from flowers, whose main components are some volatile natural products, add a variety of fragrances to our daily life.
Natural products are naturally selected and optimized by organisms over a long period of time, and often have unique structures and the ability to bind with specific targets, some of which can be used directly in the treatment of diseases.
